It turned out that as a solution to practicing by herself, Jeon Somi video called a friend to practice her lines. The helpful friend at the other end of the line was Kim Chungha.

To help practice Jeon Somis lines, Kim Chungha yells, Jeon So Mi, whats wrong with you? And Jeon Somi answers, What did I do?

Jeon Somi then requests Kim Chungha to look at her with an expression of disbelief, and Kim Chungha responds with a comical face instead.

Meanwhile, Kim Chungha recently debuted as a solo artist with her song Why Dont You Know. The two former members of project girl group I.O.I showed that they are maintaining a close friendship even after the groups disbandment.
